能性のある鋭い縁部はない。FIG. 4 shows another embodiment of the disc holder. In this case, the support members 18, 19 are clamped onto the disc 9, the flexible graphide 15 and the assembly is sealed using a flat wire 20. In this configuration, the support member 19 on the disk is a military expense that accurately determines the torque on the bolt and accurately controls the pressure.The pressure resistance of the disk is In the embodiment shown in FIG. 5, a flexible flange disk 22 is glued to a gasket 23 with the required adhesive.The disk and gasket are attached to the lower holder. 24 and place the holder on the disc and flange assembly (.
The depth of 6 is made slightly smaller than the thickness of the disk 22. If the two flanges 25.degree. 24 are tightened by the required bolts, not shown, the surfaces 27, 28 clamp the gasket 23 and the flange 29 of the disc 22 is held in the recess 26. 7 langes 29 are slightly compressed but not damaged by the pressure. Even if the bolts holding the assembly are tightened to any desired torque, the disc will not be damaged or the relief pressure will change. That is, the upper annular holder 25 is provided with a notch 30, which is not affected by changes in the torque of the assembly bolt.
The required tag attached to 3 projects through the notch. The tag shall be used to identify the disc, and shall be located eccentrically to the disc and gasket as required, with the disc facing in the opposite direction (it can be installed only in the position shown in the figure). The dome portion 31 of the metal disc combined with the present invention is continuous and smooth, so the grahyde is fully supported on the entire surface of the disc and there are no sharp edges that could tear the grahyde layer. .

加工した平な含浸円板に代えて使用できる。The use of a furanite dome attached to a metal disc increases the operating temperature of the metal disc in corrosive atmospheres.Flexible granoite is not porous and usually does not contain resin, so it is highly Highly corrosion resistant in corrosive or oxidizing atmospheres and easy to manufacture. Thus, graphide-covered metal discs can be used in place of machined flat impregnated discs.

Furthermore, in the case of the reverse buckling method, it operates within a range of 90% to 100% of the relief pressure. For comparison, the operating pressure of a flat flexible gramhyde disk is about % of the reverse buckling pressure mentioned above.

In the case of an inner diameter of m, the shape shown in Fig. 1 could be manufactured with a thickness of 0.15"1 to 15mm, and the breaking pressure was 0.25" and 6.8mm.The breaking pressure at atmospheric temperature was 100%. Therefore, at 200℃, it decreases by 15% to 85
At 400°C, it decreased by 17% to 83cm, and at 600°C it decreased by 23% to 77cm. The breaking pressure of a 100 fl disc is 12 (1068%) for a thickness of 0.15 m. Other thicknesses are also possible. Metal discs are used only in flexible granite discs for internal diameters of 0.50 mm.

When using only a 70 grahide disk without a metal member attached, the grahide is shredded when the disk breaks, and no special device for trapping the grahide is required. Figures 2.3, 4, and 6.7 i/C show cases in which a metal disk is attached to a grahyde disk. In the case of this disc, the metal disc is completely removed from the holder when it is turned over.

In a single-sided blade device, the inner blade collides with the blade when it is turned over. A second type of disc is shown in Figures 8 and 9, with the concave surface facing the high pressure. It is also possible to use a fractured disk in which the disk is fixed to a holder by welding or the like, with the concave surface facing the high pressure. In the case of a disc with score lines, the score line is on the opposite side of the graphide layer, the high pressure side of the disc is smooth, and the surface in contact with the granoite is smooth.

る。As an inverted buckling fracture disk assembly, when the grahyde disk faces the convex side to high pressure, compressive force acts on the flexible grahyde disk, and the pressure resistance of the material has a great influence. The flexible graphide disk can be directly formed into a dome shape by a simple press operation. Additionally, it can withstand repeated pressures up to 90% of the breaking pressure and has a breaking tolerance of approximately ±5 inches. The pressure from the concave side of the disk can withstand ±10% of the breaking pressure. That is, it is safe to insert the disc in the opposite direction, and
If the specified pressure is increased by 1 or 2 atmospheres, it can withstand a complete vacuum.

。Until now, granoite has always been flat, and only flat surfaces could be produced without difficult machining from blocks. All dome types used to date are made of metal. Therefore, the present invention provides for the first time a dome-shaped grahyde disk, which can be easily manufactured by press molding of flaky grahyde. Ordinary granoite disks impregnated with resin have significantly poor heat resistance at high temperatures. The flexible graphide according to the invention can be used without resin impregnation, is airtight and can be used at high temperatures. Discs are easy to manufacture.
